Default UDF for magnetite nanoparticles energy source

NPs is on a distinguished road
Hi everyone,
I'm writing my master thesis in biomedical engineering. I had to write an UDF to implement the heat generated by nanoparticles in a phantom agarose model injected with nanoparticles in Ansys fluent.
The model consist in two concentrical cylinders where the inner one is injected with nanoparticles and then the heat is generated by these one applying an external magnetic field.
The formula for the power generated by the nanoparticles is P=3.14*A*B*C*D
where A,B,C,D are constants (numeric values that I will put in).
The heat generated is so Q=P*t where t is the time for which the magnetic field is applied.
I want to study how the heat generated by the NPs in the inner cylinder spreads in the outer cylinder.
I suppose I have to use the DEFINE ENERGY SOURCE but I'm a newbye of this software and I need some suggestions.
Thank you very much
